| Abstract | Excessive exposure to Ultraviolet (UV) radiation can induce oxidative stress, premature skin aging, hyperpigmentation, and various forms of skin damage. Cassava leaves (Manihot esculenta Crantz.) are known to contain bioactive compounds such as flavonoids, polyphenols, tannins, and vitamin C, which exhibit antioxidant activity and have the potential to act as natural photoprotective agents through their ability to absorb ultraviolet radiation. Therefore, is the development of a foundation with UV protective properties is needed. This study aimed to formulate a foundation containing ethanol extract of cassava leaves as a UV-protective cosmetic preparation. The extract was incorporated into foundation formulations at different concentrations: F1 (2.5%), F2 (5.0%), and F3 (7.5%). The physical quality of the formulations was evaluated through organoleptic, homogeneity, pH, spreadability, adhesiveness, viscosity, and irritation tests. The results showed that the ethanol extract of cassava leaves could be successfully formulated into a homogeneous brown-colored foundation. The average pH values ranged from 4.79 to 5.16, spreadability from 5.77 to 5.94 cm, adhesiveness from 4.39 to 4.76 seconds, and viscosity from 2,687 to 3,405 cPs. The UV-protective activity of the foundation was determined based on the Sun Protection Factor (SPF), measured at the UV-B wavelength range of 290–320 nm. All formulations demonstrated UV protection ranging from the maximum to ultra protection categories. Formula F3, containing 7.5% ethanol extract of cassava leaves, exhibited the highest SPF value of 33.01. Analysis of variance (ANOVA) indicated that the concentration of cassava leaf ethanol extract significantly affected the SPF value of the foundation formulations. The SPF value of Formula F3 (33.01) was comparable to that of the positive control, Luxcrime Radiant Silk Foundation (SPF 33.14).
